Metabolic Research Peptides
GLP-1 receptor agonists & metabolic modulators — factory-direct, batch-traceable
Key Statistics
The metabolic peptide category is the highest-volume segment in research peptide supply — driven by global demand for GLP-1 receptor agonists. PeptideSourceHub manufactures all five metabolic peptides in-house, with synthesis capacity scaled for bulk orders. Semaglutide and Tirzepatide together account for over 40% of our B2B production volume.

Portfolio Strategy Scenarios
Distributor Portfolio
Start with Semaglutide as your anchor SKU. Add Tirzepatide for premium positioning. Introduce Cagrilintide as complementary upsell.
Private-Label OEM
Launch branded Semaglutide + Tirzepatide dual line. Differentiate with fixed-dose Cagrilintide/GLP-1 combination kits.
Research Consortium
Source all 5 molecules from one factory for protocol consistency. Batch traceability across the entire portfolio.
FAQ
What's the difference between Semaglutide and Tirzepatide?
Semaglutide activates GLP-1 receptors only. Tirzepatide activates both GLP-1 and GIP receptors. In research, dual agonism shows enhanced metabolic effects compared to GLP-1 alone. Retatrutide adds a third target (GCGR).
Do you offer fixed-dose combination kits?
Yes. We produce custom fixed-dose combinations — for example, Cagrilintide 5mg + Semaglutide 5mg in a single vial. Minimum order quantities apply for custom formulations.
What purity do your GLP-1 peptides meet?
All five products target ≥99% purity by HPLC. Lower-purity material is not released. Full analytical documentation — HPLC chromatogram, mass spectrometry data — available on request with every batch.
How does volume pricing work for bulk orders?
Tiered pricing starts at 1-3 kits, with progressive discounts at 4-9 kits, 10-24 kits, 25-49 kits, and 50+ kits. Contact our sales team for a detailed quotation based on your projected monthly volume.
